          Abstract

          Resumen: Las colillas de cigarrillo son uno de los residuos más comunes a nivel mundial. Sus componentes tóxicos y no biodegradables hacen de este un residuo peligroso y una de las causas de contaminación ambiental. Este artículo presenta los resultados de una investigación en la que se estudió la alternativa de incorporar colillas de cigarrillo en la fabricación de ladrillos de arcilla. Se elaboraron cuatro mezclas dentro de las que se incluye una mezcla patrón con contenido de 100% arcilla (LADRICOL 0%) y tres adicionales con colillas de cigarrillo en diferentes porcentajes en peso (LADRICOL 2,5%, LADRICOL 5% y LADRICOL 7,5%). Estas mezclas fueron cocidas a diferentes temperaturas y se sometieron a los ensayos respectivos para determinar propiedades físicas y mecánicas del producto terminado. Los resultados obtenidos, demostraron que, con la adición de colillas de cigarrillo en un 2,5% y una temperatura óptima de cocción de 850°C, se pueden fabricar ladrillos no estructurales tipo M, cumpliendo con los estándares establecidos en la NTC 4205-2, generando impactos positivos en el medio ambiente y reduciendo el consumo energético durante la cocción del ladrillo, en un 19,75%

          Abstract: Cigarette butts are one of the most common waste worldwide. The toxic and non-biodegradable components make cigarette butts a hazardous waste and one of the causes of pollution. This paper presents some of the results of a study on the re-cycling cigarette butts in the manufacture of clay bricks. Four mixtures were made, these include a control clay brick, with a clay content of 100% (LADRICOL 0%) and three additional mixtures incorporating cigarette butts in different percentages by weight (LADRICOL 2.5%, LADRICOL 5.0% and LADRICOL 7.5%). The mixtures were fired at different temperatures and these were tested to determine the physical and mechanical properties of the bricks. The results showed that the samples incorporating 2.5% cigarette butts content and fired at 850 °C are in compliance with the standard normative for this type of product (NTC 4205-2). Furthermore, this brick can improve the environmental quality and can reduce energy consumption during firing, by 19.75%.

            Tobacco Product Waste: An Environmental Approach to Reduce Tobacco Consumption

            Cigarette butts and other tobacco product wastes (TPW) are the most common items picked up in urban and beach cleanups worldwide. TPW contains all the toxins, nicotine, and carcinogens found in tobacco products, along with the plastic nonbiodegradable filter attached to almost all cigarettes sold in the United States and in most countries worldwide. Toxicity studies suggest that compounds leached from cigarette butts in salt and fresh water are toxic to aquatic micro-organisms and test fish. Toxic chemicals have also been identified in roadside TPW. With as much as two-thirds of all smoked cigarettes (numbering in the trillions globally) being discarded into the environment each year, it is critical to consider the potential toxicity and remediation of these waste products. This article reviews reports on the toxicity of TPW and recommends several policy approaches to mitigation of this ubiquitous environmental blight.
